Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a pretreatment device for the combustion treatment of organic waste gas. Background Technology

[0002] Industrial production processes generate large amounts of VOCs-containing industrial waste gases, including fugitive volatile gases, gases emitted during space ventilation, breathing gases, and production emissions. These waste gases typically contain various organic pollutants and impurities, such as hydrocarbons, alcohols, ethers, and esters. Direct emission of these gases not only causes severe air pollution but may also harm human health, such as irritating the respiratory tract and nervous system, and even posing risks of carcinogenesis, teratogenesis, and mutation.

[0003] The combustion treatment of organic waste gas involves introducing the waste gas into an incinerator through transport pipelines, where combustible and harmful substances are converted into harmless or easily treatable substances through thermal oxidation before being discharged. Organic waste gas generated in the chemical industry is volatile; its concentration may vary depending on the season and time of day. The inlet concentration of the waste gas directly affects the treatment efficiency of the waste gas treatment facilities, the service life of the incinerator, and the safety of equipment and personnel. Excessive waste gas concentration can lead to incomplete combustion, increased fuel consumption, excessive emissions, and excessively high furnace temperatures, causing damage to furnace facilities. If the waste gas concentration exceeds its explosion limit, it can lead to an incinerator explosion with serious consequences. Utility Model Content

[0004] The purpose of this invention is to address the problems in the existing technology where excessively high waste gas concentrations may lead to incomplete combustion, increased fuel consumption, excessive exhaust emissions, and excessively high furnace temperatures, causing damage to furnace facilities. Furthermore, if the waste gas concentration exceeds its explosion limit, it may lead to an incinerator explosion and serious consequences. Therefore, this invention proposes a pretreatment device for the combustion treatment of organic waste gas.
